Just a quick observation hardware wise, on the Palette VL, when you're sitting at the desk, if you run a submaster to full, the handle pretty much covers the number completely.

Annoying if you're just using one or two, but if you're using a bunch for busking or whatnot, can become a problem, especially on the 64. Perhaps we could screen print the numbers onto the button? just an idea.

I would suggest a Brother P-Touch label maker using the black tape with white writing. I'm using the 12mm to great effect on my three Light Palette Lives. I've used it to mark Power switch, USB, Name, and IP address on each console. The shiny black blends in with the console yet give a bit of contrast to help see the labels.

So far I haven't had a problem with them slipping around but they have only been on the console for a month now.

There is about 8mm to 9mm between the top of the fader and the bottom of the button for the next row.

Get some of this plastic extrusion like this from your nearest office/stationary supplier:http://www.techplas.com.au/products/binder.htm
...and fix it "opening up" between the fader banks. Your labels will now be conveniently placed, easily replaced and easily visible.
